APPLICATION OF 3-D BEACH DEFORMATION NUMERICAL MODEL TO A FIELD SITE OF SANDY BEACH INCLUDING EXPOSED ROCK AREA AROUND A HARBOR

摘要

A practical numerical model for 3-D beach deformation due to multi-directional random waves is developed by modeling the suspended and bed sediment transports passing over exposed rocks in the case of thinner sand layer thickness on the rocks. Next, these sediment transport models are verified by beach model tests around exposed rocks using multi-directional random waves. Next, this numerical model is applied to a field site of sandy beach including exposed rock area around a harbor and verified.
